I have used Samsung now for around 6 years. In general they are pretty good all round and the A51 is no exception. It has a great screen, a good camera system and easy, solid operating system. Battery life is a bit average (may be the Covidsafe app!) but I am overall happy with the phone. Unfortunately there is a serious gremlin in the fingerprint scanner where it plain refuses to read one or more fingers, yet a few minutes later it works perfectly. I took the first A51 back to the dealer reasoning I had a dud, but this one is just as bad. Hopefully something Samsung can fix with a software upgrade.
